// 签订代理， 指定代理人，实现协议方法
// 指定代理人， 在Xib中可以通过控件向File‘s Owner去指定 （相当于 self.userTextField.delegate = self）
//只需要签订代理， 实现代理方法
@interface FirstXibViewController () <UITextFieldDelegate>
//IBOutlet  修饰的属性， 是xib／SB中的控件
//1.实心圆圈说明以关联对象

@property (weak, nonatomic) IBOutlet UITextField *userNameTextField;
//2.空心圆圈说明未关联对象
@property (weak, nonatomic) IBOutlet UITextField *passwordTextField;
//3.Xib／SB 中控件与VC／自定义cell 关联后如果属性被删除，对应控件的关联也应删除（右键查看控件 Refercening IBOutLets）
//如果控件非常多，出现问题，无从下手
//查看崩溃信息中
//关键的key：userNameTextField
//在搜索栏， 搜索关键key userNameTextField
